Answer:
see explanation
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y-intercept )
here m = 
and b = 13, hence
y = x + 13 ← in slope- intercept form
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and AB, C are integers )
multiply all terms in the slope-intercept form by 3
3y = x + 39 ( subtract 3y from both sides )
0 = x - 3y + 39 ( subtract 39 from both sides )
x - 3y = - 39 ← in standard form
Answer:
2/8
Step-by-step explanation:
To find an equivalent of a fraction, multiply numerator and denominator by the same value:
1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8
Let a be the amount of peanuts; and
Let b the amount of walnuts
Equation 1 would be: A + B = 100
249a + 389b = 319 (100)
Equation 2 would be: 249a + 389b = 31900
From equation 1:
a = 100 – b
249 (100 – b) + 389b = 31900
24900 – 249b + 389b = 31900
140b = 7000
b = 50 lbs
then from equation 1:
A + 50 = 100
A = 50 pounds
